    • @ulysses1904
      @ulysses1904 3 года назад

      ​@@sulaimandanish4561 Some of things I emphasized in the interview were:
      1. I passed the Microsoft exam for Writing SQL Server Queries for 2012/2014
      2. My Excel skills, which you will be using constantly in conjunction with SSMS
      3. I have SQL Server Development version along with Visual Studio on my home computer and am familiar with writing basic packages in SSIS and writing basic reports in SSRS
      4. Watch countless videos and read articles by Venkat, Adam Machanic, Brent Ozar, Itzek Ben-Gan, Bert Wagner, etc and all the free material made available by Microsoft MVPs. And download their code examples.
      5. Emphasize any data management you might have done in any job you have had in the past.
      It took me 3-1/2 years of self-study to move from IT break/fix support to SQL development but it was worth the effort.

    "SQL Server uses a B+-Tree index not the traditional B-Tree index. There are two major differences between traditiona B-Tree index and B+-Tree index:
    In a B+-Tree index, all of the data is in the leaf level pages. Only key values and pointers exist in the root and intermediate levels.
    In a B+-Tree index, there are pointers which point to the next and last page in the level.
    With each page pointing to the page ahead and behind you can do range scans without having to travel up and down the index levels.
    On Wikipedia here, you will find SQL Server is one of many modern database engines using B+, a reference has been cited in the page.
    When you read Microsoft documentation here, you know by the description how indexes work on SQL Server that B+ is used and not the traditional B-tree."

    Hi Kudvenkat. Thanks for the video. Can you please make a video to show how to insert into, select delete and update several one to many tables. For example a table student, teacher, address, phone and email. Both the teacher and the students can have several phone number email, phone and address. Thank you
